error instantiating std::map on an incomplete type
--------------------------------------------------
Key: STDCXX-152
URL: http://issues.apache.org/jira/browse/STDCXX-152
Project: C++ Standard Library
Type: Improvement
Components: 23. Containers
Versions: 4.1.2, 4.1.3
Environment: all

I am trying to use Boost built using stdcxx on Solaris. I was able to build
the date_time
library but when I try to compile a test program I end up with errors related
to incomplete
types. I have narrowed the issue to the following code
#include <map>
#include <string>
using namespace std;
template <class T>
struct C {
typedef multimap<T,C> maps;
typedef typename maps::value_type value_type;
};
int main () {
C<std::string> c;
}
When I compile using the default Sun CC libraries or rwtools7_std or
stlport4, the code
compiles fine. But when I compile using stdcxx, I end up with the following
errors.
